Our invention relates to building structures. It has to do, moreparticularly, with building structures which are made of sheet metal.

Buildings of this type are put to a wide variety of uses. It isfrequently-desirable to insulate these buildings for various reasons.For instance, they are sometimes usedas workshops or for storage ofmaterials that may be injured by temperatures which are too low or thatmay be injured by condensation moisture gathering upon the interior ofthe walls of the building. It is also sometimes necessary to insulate abuilding of this type in such a manner as to protect the interior of thebuilding from excessive heat, due to the rays of the sun striking thebuildingor due to other causes.

Heretofore, some attempt has been made to insulate metal buildings bothof the standard type and the non-standard type. The most common methodof accomplishing this hasbeen to erect buildings in the usual manner,then apply wooden strips upon the interior to the structural frame towhich the metal sheets are attached and, finally, to attachtheinsulating material to these wooden strips. The application of thesewooden strips is laborious because it is usually necessary to notch thestrips to fit around the various steel members. This structure resultsin an air space between the plaster-board or other insulating materialand the sheeting which is usually of such width that it is possible forair currents to become started and thus cause more or less ventilationwhich tends to reduce the insulating properties of the entrained air.

This practice of applying the insulation after the building is erectedhas, in the past, required removal of the insulation before the buildingcould be dismantled. Furthermore, it has also required destruction ofmuch of the insulating material or such injury thereto as to prevent itssubsequent use.

One of the objects of our invention is to provide a means for insulatinga metal building and a means for applying the insulation to a standardmetal building in such manner that the efiectiveness of such insulationwill be increased. Another object of our invention is to provide amethod of applying insulation to a standard metal building withoutincreasing the erection cost of the building. Still another object ofour invention is to provide a means for insulating a metal buildingwhich is of such form and so applied that the building may bedisassembled, transported to a new location, if desired, and thenreassembled without either injuring or removing the insulation.

In obtaining these and other objects, we have conceived the idea ofproviding a panel for standard sectional buildings which embodies both asheeting unit and insulating means. The structure of our device is suchthat it may be constructed-as an entity in the shop and transported andinstalled in a manner similar to the installation of panels which arenow being marketed without insulation.

Our invention preferably takes the form of a panel structure to which isapplied a sheet or sheets of metal lined with commercial insulatingmaterial in sheet form. The

insulating material is preferably placed in between the structuralframework and the metal sheeting of our panel and in intimate contactwith this metal sheeting. It is held in place by the metal clamps andrivets or bolts which holdthe metal sheeting and the cap strip inassembled position uponthe skeleton framework of the panel.

The preferred embodiment of our inven tion is shown in the accompanyingdrawings wherein similar characters of reference designate correspondingparts and wherein:

Figure 4 is a sectional view similar to Figure 3 but showing ourinvention as embody.- ing corrugated sheeting.

Figure 5 is a sectional view showing a mod ified form of the means forattaching the insulating material to the sheeting. 1

Referring to the drawings, we have shown a structural panel comprisingtop andbottom horizontal girts 1, vertical side columns 2 and anintermediate girt 3. These girts and columns preferablytake the form ofangle irons and are so connected together as to form a skeletonframework of rectangular form.-

' thereon is the metal sheet which is preferably comprised of aplurality of panels 5 joined by cap strips 6 and interlocking clamps 7.8 and 9 extending entirely through the insulating material.

The clamps 7 are of the type preferably used for attaching the metalsheets and cap strips to the intermediate girts 3. This clam is providedwith a T-shaped head, like the clamp shown in Figure 3, and with a.bifur cat-ed shank designed to embrace the out.- standing flange of theangle iron constituting the intermediate girt. Inasmuch as it is usuallydesirable to cut an opening in the insulating material for the passageof this clamp 7 through it, we preferably plug this opening with a.pieceof insulating material,

as at 10.

The clamps 8 are what is known as J-clamps and are provided with aT-head, as shown in Figure 3. and with a shank that is bent laterallyafter passing throughthe insulating material so as to embrace the girts1 and hold the cap strip firmly .in position. \Ve preferablyprovide-plugs 11 of insulating material for fitting in the openingswhich have been cutv through the insulating material for the passage ofthe shanks of the clamps 8.

The clamps 9 are similar in construction to the clamps 8. However, theyare preferably supplemented by bearing strips 12 which are interposedbetween the bent over portions of the shanks of the clamps and theinsulat iug material. The openings through which these clamp shanks passare, likewise, closed by plugs of insulating material 13.

The metal sheeting and the insulating material are additionally securedto the skeleton framework by bolts and nuts or rivets which pass throughthe girts 1 and 3, and the columns 2.

In Figure 4 of the drawings, we have shown.

15 are shown as being assembled with the insulating material 16. Thesheeting and insulating material are held in assembled relation by meansof rivets 17 and a metal strip 17 It will be understood that any type ofsheeting and any form of fastening means may be employed. I

A modified form of means for attaching the insulating material to thesheeting is shown in Figure 5. In this figure a T-head bolt 18 isapplied to the sheeting and cap strip to serve the same pur ose as theclamps 9. A nut 19 serves to 1101 the cap strip and the metal sheets inassembled relation. The shank of the bolt 18 extends through a hole inthe insulating material and a washer or strip 20, preferably of metal,and nut 21 serve to hold the insulating material to the sheeting. Itwill be seen that we have provided a unitary structure in the form of aninsulated panel. This insulated panel may be incorporated in a buildingstructure or removed therefrom as an entity. It may be completelyfabricated in the shop at the time of assembly which is, of course, thetime most favorable for doing this work in the cheapest and mosteconomical manner. Practically no field work is necessary over and abovethat which is usually required in assembling panels for non-insulatedstandard buildings.

and WOl'kIlltll'l-llkG appearance and when it is found desirable to movethe building, the panels'can be unbolted and moved without injury to theinsulating material. In other words, the entire building can be salvagedand used over and over again. Buildings constructed of our insulatedpanels may be readi- 'ly heated in an economical and efficient mannerduring the colder months. During the hotter months, the interiorof thebuilding is protected "against undue heat due to the rays of'the sun.Likewise, the gathering of condensation moisture on the metal sheets,due to the difference between the temperatures on the outside and insideof the building, is pre eluded. In fact, our invention provides aneconomical means of. overcoming practically all the objections which areordinarily raised to the standard steel building for. use of fac-Furthermore, the structure presents a neat tory buildings, warehousesand transformer houses and other types of electrical equipment wherecondensation, or moisture is an objectionable feature.

Having thus described our invention, what we claim is:

1. Building structure comprising a skeleton framework constructed ofangle irons, a metal-sheeting unit; constructed of a plurality of panelsof metal sheeting and cap strips, a sheet of insulating materialinterposed between said metal sheeting unit and said framework, andmeans passing through said sheet of insulating material for securingsaid framework, said metal sheeting unit and said sheet of insulatingmaterial being secured together to form a panel.
